The Inaugural Ironman 70.3 Washington is Coming to Maple Valley

While Washington state is known for playing host to many sporting events, this year, there’s a new race on the calendar.

For the first time ever, the community of Maple Valley will be home to the Ironman 70.3 Washington — a premier event in the Ironman community.

On Sunday, September 19th, hundreds of athletes will descend on the area, ready to compete for the distinction of being called an Ironman.

This incredible weekend promises to be an exciting few days for both athletes and spectators, and we’re looking forward to welcoming so many people to Maple Valley.

With a thrilling race and plenty of local fun and flavor, the inaugural Ironman 70.3 Washington is shaping up to be the perfect opportunity to showcase the best of what the Evergreen State has to offer.

“This means so much to the City of Maple Valley and we couldn’t have done it without our community partners!” Mayor Sean Kelly.

Let’s take a look at what you can expect from Ironman 70.3 Washington.

What’s an Ironman, Anyway?

If you’re not familiar, an Ironman is a long-distance triathlon. It involves a combination of 2.4 miles of swimming, 112 miles of biking and 26.2 miles of running.

Often dubbed the hardest and most demanding single-day event for athletes, competitors traverse 140.6 miles, burning upwards of 10,000 calories over the course of their race.

A half Ironman — usually referred to as an Ironman 70.3 like the race being held in Maple Valley — sees competitors completing half the distance of a full Ironman, including 1.2 miles of swimming, 56 miles of biking, and 13.1 miles of running. These races are ideal for those newer to participating in Ironman events.

Ironman events are held across the globe throughout the year. From Germany and Morocco to Auckland and Taiwan, those who are part of the Ironman community are known for traveling far and wide to participate in these races.

As one would imagine, training for an Ironman race is a huge commitment, with racers working for months to be in race-ready shape. The level of effort and dedication required to participate in these events is huge, so having friends, family, and spectators along the course route to offer support is a key part of every Ironman event.

That’s exactly why we’re so excited that for the first time ever we’ll be welcoming Ironman Washington to the community of Maple Valley this fall!

Let’s take a look at what you can expect from the inaugural Ironman 70.3 Washington, as both a participant and a spectator.

What Athletes Need to Know

The Ironman 70.3 Washington event is being hosted in Maple Valley, a smaller suburb just outside of Seattle. Centered around local gem Lake Wilderness Park.

“We are excited to showcase the natural beauty of our area. We are certain that participants (and spectators) of the inaugural Ironman 70.3 Washington will love the swim, bike and run course that have been selected for this race.” – Laura Philpot, Maple Valley City Manager

The Maple Valley and Black Diamond areas are known for their large and calm lakes, endless mountains and hills, and dynamic trails — creating a challenging and scenic Ironman course.
